I went into my computer, clicked on the printer icon and opened it up. Then I was able to scan simply by pressing scan on the icon, It took me thru the Print wizard and I was able to scan without any error message. So now, my printer will print, scan , copy and sort. I am still enjoying the idea of the all in one printer. So, thanks for your offer of help.

A)1 Unplug the printer.2. Uninstall the drivers.3. Reboot the machine.4. Go to the lexmark site and download the drivers.5. Install the new drivers.

B)You will get the "CANNOT RETRIEVE APPLICATION LIST" if your pc blocks
the communication from the printer. This can be configured in your
personal firewall. This can be Windows Firewall (found in Control
Panel, Security Center), Symantec Client Firewall or similar. Depending
on the configuration of this firewall you might or might not get pop-up
messages from the firewall during installation. These pop-ups will
allow you to permanently allow for this incoming communication. But
your firewall might be set not to let you decide anything which will
typically mean that the calls will be blocked out. This will often be
the case if you have a company laptop configured by the company IT
dept. You might then have to ask an admin to add exceptions the
applications used by Lexmark as the configuration might not be open for
you to change.

First thing to do is try to check if your windows XP is a 32 or a 64-bit. You can do this by right clicking the mouse on My Computer icon and then left click on properties. Now try to load the right and updated driver. If it still won't work. Go to Control Panel>administrative tools>services>scroll down and look for WIA ( Windows Image Acquisition). when you double click on it you should see it it is running, stopped, make sure that it is started. If still won't work try using other application like paint.

Please follow the steps given below to add applications to Imaging studio:
1. Open the Imaging Studio and then click "scan," after the scanned document appears as a preview.
2. Click "Other Software" at the bottom.
3. That will open up the list of application list, to modify the application list, click on "Modify Application List".
4. Please add the application you want to scan and click on "Close."

I had same problem on windows vista. The imaging studio used to work on Win XP but not on Vista. I tried the CD that comes with the printer and downloaded the driver from lexmark. In the end I foind that:In explorer go to c:\drivers\printer\4300\applications and click on the setup.exe file. It finishes the install and then the next time you go to start, programs, lexmark center you get the full drop list of the All in1, imaging studio, photo center etc.

Make sure that the Lexmark Imaging Studio program is running. This was installed when you set up your printer.If you see the multi-colored icon in your task bar for Lexmark Imaging Studio then try pressing the scan mode button twice. You should be able to scan then.

I gave gotten it to retrieve the applications list by opening Lexmark Imaging Studio while it was searching, I AM however still unable to scan it connects to my comp I tell it to save as a file and it goes "Requesting Scan" then "Scan Request Failed"

I have the Lexmark X3550 with the WiFi option board installed (makes it same as the model X4550) and get the “cannot retrieve applications list” message on one of the five computers connected to my router (Linlsys WRT54G V8) and using wireless printing and scanning. Just like everyone else with a similar Lexmark WiFi printer/scanner, I can print wireless, but cannot get the wireless scanner to work on one of my PCs.

The fix, in my case, was to change the Lexmark network name as follows.

1. Launch Lexmark Imaging Studio.
2. Right-Click on “View or change network settings”.
3. Enter a new network name in the first box shown. (This box contained the correct network name for my PC, but another name was needed to make the scanner work. I simply added “-lex” at the end of the current network name.)
4. Right-Click OK. You should return to the Imaging Studio screen.
5. Close the Lexmark Imaging Studio window. (The tray icon should remain at the screen lower right.)
6. On the printer, press the Scan Mode button.
7. On the printer’s display screen, select the Computer Name that you entered for the new network name. Just use the arrow buttons until the exact name is shown.
8. Press the Check button.The display screen should show “Downloading Applications List”. Within about 10 seconds the message should change to “ *Scan to Computer ”. Wireless scanning should now work.
9.. Press the Start Color or Start Black button.“Requesting Scan” will be shown. After a few seconds scanning will start. The process is a bit slow.
10. After a while you may see an empty small Lexmark window onscreen. Later, the Lexmark Imaging Studio will appear onscreen, then change to show many options and features. An image of the scanned item will appear in a Lexmark window. Save and/or edit the image. Another scan can be done by pressing the printer’s Check button again. Be sure the correct computer name is shown on the printer’s display.

That’s it. A new computer name was the solution. Your PC and printer may require a restart (power off) after changing the “computer name”.

The fix, in my case, was to change the Lexmark network name in their Imaging Studio application. This worked for several weeks, but now I get the “cannot retrieve applications list” message again. I have not fixed the new error yet, but changing the network name may work for you. Here are the steps to change the Imaging Studio network name.
